Transcriptional activity of AP-1, NF-κB, IRF2, CREB, and GR as assessed by TELiS bioinformatics analysis of transcription factor binding motif prevalence in promoter DNA sequences of genes showing ≥ 1.25 fold differential expression in unstable vs. stable social conditions. Two-tailed p values were derived from comparing mean (log2-transformed) prevalence ratios for each transcription factor (i.e., relative frequency of promoter sites among up-regulated genes / frequency among down-regulated genes) using bootstrap-derived standard errors.
